[0013] Meanwhile, this invention also discloses a construction method for assembling double-block sleepers using an intelligent sleeper-splitting assembly trolley, characterized by the following steps: Step 1: Placement of the intelligent sleeper assembly trolley and loading of the double-block sleepers: Step 101: Move the intelligent pillow-separating trolley to the required construction area; Step 102: Move the front moving frame towards the rear moving frame and load the packaged double-block sleepers onto the sleeper tray. Step 103: The moving frame of the train head moves in the opposite direction so that the moving frame of the train head is reset to be located outside the sleeper tray; Step 104: The multiple transverse clamping components on the clamping and lifting mechanism correspond to the multiple double-block sleepers located on the top layer; Step 2: Clamping, lifting, and placing the double-block sleepers: Step 201: The clamping and lifting mechanism clamps and lifts the multiple double-block sleepers on the top layer; Step 202: The gripper mechanism clamps one of the double-block sleepers after it has been lifted. Step 203: The moving frame of the car head moves towards the middle sleeper car body, driving the double-block sleeper clamped by the gripper mechanism to move backward until the double-block sleeper moves to the designed position on the middle sleeper car body. Step 204: The gripper mechanism lowers the clamped double-block sleeper to the designed position; Step 205: The head moving frame moves in the opposite direction so that the head moving frame is reset outside the sleeper tray. The gripper mechanism clamps the next double-block sleeper after it has been lifted, and according to the methods of steps 203 and 204, the next double-block sleeper is clamped to the next designed position on the middle sleeper car body until the uppermost multiple double-block sleepers are clamped. Step 206: Following the methods in Steps 201 and 205, clamp, lift and place multiple double-block sleepers on the next layer until the double-block sleepers on the middle sleeper car meet the laying design requirements. Step 3: Assembly of the double-block sleepers and double-block fine-tuning rail panels: The rear moving frame moves along the length of the middle sleeper car body, and during the movement of the rear moving frame along the length of the middle sleeper car body, the robotic arm installs the double-block sleeper accessories so that the double-block sleeper and the double-block fine-tuning track panel are assembled into a whole.

[0014] The above construction method is characterized by the following: Step 201, the specific process is as follows: Step 2011: Control the extension of multiple transverse hydraulic rods. The extension of multiple transverse hydraulic rods pushes the L-shaped clamping piece close to the uppermost multiple double-block sleepers until the clamping block is tightly attached to the two outer end faces of the double-block sleeper, and the bottom surface of the truss of the double-block sleeper is attached to the horizontal surface of the L-shaped clamping piece. The limiting rod is just inserted into the web plate at both ends of the truss of the double-block sleeper. Step 2012: Control the upper lifting cylinder to retract. The retraction of the upper lifting cylinder drives the material support plate and the multiple double-block sleepers clamped by the material support plate to rise synchronously, so that the bottom height of the double-block sleepers is higher than the horizontal part of the L-shaped lifting claw; wherein, when the material support plate rises, the guide sleeve rises synchronously along the guide rod. Step 202, the specific process is as follows: Step 2021: Control the extension of the hook claw cylinder, and drive the gripper mechanism and its L-shaped lifting claw to move along the length of the upper slide rail through the transverse component until the L-shaped lifting claw moves to the bottom of the double-block sleeper located at the rear edge of the gripping and lifting. Step 2022: Control the hook claw cylinder to retract. The retraction of the hook claw cylinder drives the L-shaped lifting claw to rise until the hook claw cylinder returns to its original position. Step 2023: Control the extension of the limit cylinder. The extension of the limit cylinder pushes the limit block down until the limit block fits against the two inner end faces of the double-block sleeper.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention has a simple structure, reasonable design, and is easy to install and deploy, and is convenient to control, realizing the separate sleeper of the double-block sleeper.

[0016] 2. The car head assembly used in this invention can move along the length of the car body with the middle sleeper. Through the reciprocating movement of the car head assembly, multiple double-block sleepers can be clamped and transported, reducing manual intervention and thus improving construction efficiency.

[0017] The rear assembly can move along the length of the car body with the middle sleeper. Through the reciprocating movement of the front assembly and the cooperation of the robotic arm, the installation of the double-block sleeper components into double-block sleepers is realized, which improves construction efficiency and intelligence.

[0018] 3. The loading and lifting mechanism used in this invention includes an outer bottom frame and a lower lifting compensation mechanism. This is to allow the moving frame of the car head to move towards the middle sleeper car body and load the packaged double-block sleepers onto the sleeper tray. The lower lifting compensation mechanism is designed to lift the outer bottom frame and the double-block sleepers when the clamping lifting mechanism cannot hold the bottom double-block sleeper, thereby achieving height compensation adjustment of the bottom double-block sleeper and facilitating clamping by the clamping lifting mechanism.

[0019] 4. The clamping and lifting mechanism used in this invention can move up and down along the height direction of the moving frame of the car head, so that multiple transverse clamping parts on the clamping and lifting mechanism and multiple double-block sleepers of each layer are clamped accordingly; in addition, after multiple double-block sleepers are clamped, they rise with the clamping and lifting mechanism, away from the next layer of double-block sleepers, thereby facilitating the operation of the gripper mechanism.

[0020] 5. The gripper mechanism used in this invention is used to grip and clamp each layer of double-block sleepers on the clamping and lifting mechanism one by one. As the moving frame of the car head moves towards the middle sleeper car body, the gripper mechanism drives the clamped double-block sleepers to move backward until the double-block sleepers move to the designed position on the middle sleeper car body and the gripper mechanism lowers the clamped double-block sleepers to the designed position, thus meeting the requirements of intelligent sleeper separation.

[0021] 6. The rear movable frame of the present invention is equipped with an accessory rack, on which threaded spikes, elastic clips, gauge baffles, rubber pads, and height adjustment pads are sequentially arranged. This is so that the fasteners required for the sleepers can be installed on the double-block sleepers and the rails of the double-block fine-tuning rail panel can be installed. The double-block sleeper accessories and the double-block fine-tuning rail panel can be assembled by connecting the rails and the double-block sleepers.

[0022] 7. The construction method for assembling the double-block sleepers of the present invention is simple, convenient and easy to control, and realizes the assembly of double-block sleepers and double-block fine-tuning track panels.

[0023] 8. The ballastless track method of the present invention has good performance. First, the intelligent sleeper combination trolley is placed and the double-block sleepers are loaded. Then, the double-block sleepers are clamped, lifted and placed. Next, the double-block sleepers and double-block fine-tuning rail panels are assembled. The operation is convenient, the degree of intelligence is high, and the manual intervention is reduced.

[0024] In summary, this invention is reasonably designed. By clamping, lifting, and placing the double-block sleepers, the double-block sleepers can be separated into individual sleepers. The separated double-block sleepers and double-block fine-tuning rail panels are then assembled into a whole. Subsequently, the double-block sleepers and double-block fine-tuning rail panels are installed as a whole, which can quickly complete the construction of double-block sleepers, reduce frequent manual intervention, save manpower and material resources, and improve construction efficiency.

The cylinder sleeve 307 includes an upper flat plate 3071 installed on the hoisting support plate 308, a sleeve 3072 set on the top of the upper flat plate 3071, and two guide sleeves 3073 set at the bottom of the upper flat plate 3071. The cylinder body of the hook cylinder 305 is embedded in the sleeve 3072. The telescopic rod of the hook cylinder 305 passes through the sleeve 3072 and the bottom of the upper flat plate 3071 and connects to the top of the hoisting beam 302. A connecting plate 3074 is provided between the two guide sleeves 3073.

[0061] In this embodiment, when used in practice, the hoisting beam 302 is provided with an upper guide rod 306 that extends into the guide sleeve 3073.

There are two upper slide rails 310, which are set on the top crossbar of the front frame 102, and the length direction of the upper slide rails 310 is arranged along the driving direction of the front frame 102.

[0065] In this embodiment, during actual use, one end of the intermediate vehicle frame 9 is connected to the crossbeam frame 504 of the outer bottom frame 5, and the other end of the intermediate vehicle frame 9 is connected to the rear underframe 16.

[0066] In this embodiment, during actual use, the ends of the vertical frame beam plate 901 and the middle U-shaped plate 903 are provided with connecting expansion plates 906, which are connected to the crossbeam frame 504 of the outer bottom frame 5 at both ends and the rear chassis 16 through the connecting expansion plates 906.

[0067] In this embodiment, during actual use, the end of the horizontal plate 902 is provided with a clearance groove near the middle rack 905, so that both the front moving frame 1 and the rear moving frame 31 can move along the middle rack 905.

[0068] In this embodiment, in actual use, the traveling wheels include two first traveling wheels 13 near the rear moving frame 31 and two second traveling wheels near the front moving frame 1. The first traveling wheels 13 and the second traveling wheels are both mounted on both ends of the horizontal plate 902 through wheel seats and bearings. The two ends of the horizontal plate 902 are provided with end boxes 907 for the first traveling wheels 13 and the second traveling wheels to be embedded and installed.

[0069] In this embodiment, during actual use, the end box 907 is equipped with a hydraulic motor that drives the first traveling wheel 13 to rotate.

[0070] In this embodiment, during actual use, a steering cylinder 14 is provided on the inner side of the vertical frame beam plate 901. The fixed end of the steering cylinder 14 is installed on the inner side of the vertical frame beam plate 901, and the wheel seat of the first traveling wheel 13 is connected to the telescopic end of the steering cylinder 14 through a connecting ear.

[0071] By setting a steering cylinder 14, the extension and retraction of the steering cylinder 14 drives the first traveling wheel 13 to rotate through the wheel seat, thereby adjusting the steering of the first traveling wheel 13. In this way, under the steering adjustment of the active wheel, its second traveling wheel can also adaptively steer.

[0072] In this embodiment, during actual use, a bottom crossbeam is provided at the bottom of the horizontal plate 902, and a hydraulic oil tank 15 is provided on the bottom crossbeam to provide hydraulic oil.

[0073] like Figure 13 As shown in this embodiment, in actual use, the moving frame 1 of the vehicle head is provided with a sliding block 204 that cooperates with the intermediate slide rail 904 and the vehicle head stopping slide rail 507.

[0074] In this embodiment, in actual use, the structure of the rear moving frame 31 can refer to the front moving frame 1, and is also provided with a traveling slider 204 that cooperates with the rear stopping slide rail 18 and the middle slide rail 904. The rear travel drive mechanism 32 can refer to the front travel drive mechanism 2, and is equipped with a travel motor reducer 203 and a gear 202. The travel motor reducer 203 drives the gear 202 to rotate, and the gear 202 meshes with the intermediate rack 905 and rolls along the intermediate rack 905, thereby driving the rear moving frame 31 to travel along the rear stopping slide rail 18 and the intermediate slide rail 904; Similarly, the front travel drive mechanism 2 drives the front moving frame 1 to travel along the front stopping slide rail 507 and the middle slide rail 904.

[0075] In this embodiment, during actual use, the front parking slide rail 507, the middle slide rail 904 and the rear parking slide rail 18 are connected in sequence as a whole and are at the same horizontal height, so that the front moving frame 1 can slide from the front parking slide rail 507 to the middle slide rail 904, or return from the middle slide rail 904 to the front parking slide rail 507. The rear movable frame 31 can slide from the rear stopping slide rail 18 to the middle slide rail 904, or return from the middle slide rail 904 to the rear stopping slide rail 18.

[0076] In this embodiment, during actual use, the intermediate rack 905 is located between the rear chassis 16 and the outer bottom frame 5. The rear moving frame 31 is reset and rests on the rear chassis 16. When the sliding block of the rear moving frame 31 slides onto the rear resting slide rail 18, the gear in the rear walking drive mechanism 32 does not exceed the connection between the rear chassis 16 and the intermediate body frame 9. Similarly, when the front moving frame 1 is reset and rests on the outer bottom frame 5, and the sliding block of the front moving frame 1 slides onto the front resting slide rail 507, the gear in the front walking drive mechanism 2 does not exceed the connection between the outer bottom frame 5 and the intermediate body frame 9. The rear underframe 16 and the outer bottom frame 5 limit the reset distance of the rear moving frame 31 and the front moving frame 1, preventing the rear moving frame 31 and the front moving frame 1 from slipping off the slide rail, and also preventing the gear 202 from rolling off the intermediate rack 905, thereby improving the repeatability of reciprocating movement.

[0077] In this embodiment, during actual use, the insertion positions on the accessory rack 802 can be adjusted as needed, or the size of the insertion positions can be changed according to actual needs; secondly, insertion holes, partitions or partitions can be provided in the insertion positions on the accessory rack 802 to realize the insertion of threaded spikes, spring clips, gauge baffles, rubber pads, and height adjustment pads, and to prevent fasteners from falling over.

[0078] In this embodiment, in actual use, the rotary power mechanism 814 can refer to the rotary power mechanism of the intelligent device and method for fastening railway track fastener bolts in patent CN202110934532.2 to realize the fastening or loosening of fastener bolts, i.e., threaded track spikes.

[0079] In this embodiment, it should be noted that the number and orientation of the structures can be adjusted according to construction requirements and are not specifically limited.

[0080] In this embodiment, it should be noted that the hydraulic outriggers 508 at the front, 12 in the middle, and 17 at the rear are provided to support and place the front assembly 10, the middle cushion body 20, and the rear assembly 30 after the vehicle is moved into place.

[0081] In this embodiment, it should be noted that, in actual use, a rubber anti-slip layer can be added to the side of the clamping block 707 near the double-block sleeper 401.

[0082] In this embodiment, it should be noted that, in actual use, an L-shaped collision block 40 is provided at the end of the intermediate vehicle frame 9 near the front assembly 10, and the horizontal part of the L-shaped collision block 40 is installed at the top end of the vertical frame beam plate 901 of the intermediate vehicle frame 9.

[0083] In this embodiment, the L-shaped collision block 40 is provided so that when the double-block sleeper 401 clamped by the gripper mechanism 3 moves backward, the double-block sleeper 401 clamped by the gripper mechanism 3 is first lowered and moved to contact the vertical part of the L-shaped collision block 40, so that the vertical part of the L-shaped collision block 40 collides with the clamped double-block sleeper 401, thereby ensuring that the clamped double-block sleeper 401 is horizontally arranged in the length direction. After that, the double-block sleeper 401 clamped by the gripper mechanism 3 is raised and reset and moved backward until the double-block sleeper 401 moves to the designed position on the middle sleeper car body 20.

[0084] like Figure 14 The construction method for assembling two-piece sleepers, as shown, includes the following steps: Step 1: Placement of the intelligent sleeper assembly trolley and loading of the double-block sleepers: Step 101: Move the intelligent pillow-separating trolley to the required construction area; Step 102: The front moving frame 1 moves toward the rear moving frame 31 to load the packaged double-block sleepers onto the sleeper tray 4. Step 103: The front moving frame 1 moves in the opposite direction so that the front moving frame 1 is reset to be located outside the sleeper tray 4; Step 104: Multiple transverse clamping components on the clamping and lifting mechanism 7 correspond to multiple double-block sleepers located on the top layer; Step 2: Clamping, lifting, and placing the double-block sleepers: Step 201: The clamping and lifting mechanism 7 clamps and lifts the multiple double-block sleepers 401 on the top layer; Step 202: The gripper mechanism 3 clamps one of the double-block sleepers 401 after it has been lifted. Step 203: The car head moving frame 1 moves towards the middle sleeper car body 20, driving the double-block sleeper 401 clamped by the gripper mechanism 3 to move backward until the double-block sleeper 401 moves to the designed position on the middle sleeper car body 20. Step 204: The gripper mechanism 3 lowers the clamped double-block sleeper 401 to the designed position; Step 205: The head moving frame 1 moves in the reverse direction so that the head moving frame 1 is reset outside the sleeper tray 4. The gripper mechanism 3 clamps the next double-block sleeper 401 after it has been lifted, and according to the methods of steps 203 and 204, the next double-block sleeper 401 is clamped and placed at the next designed position on the middle sleeper body 20 until the uppermost multiple double-block sleepers 401 are clamped. Step 206: Following the methods of steps 201 and 205, clamp, lift and place multiple double-block sleepers 401 on the next layer until the double-block sleepers 401 on the middle sleeper car body 20 meet the laying design requirements. Step 3: Assembly of the double-block sleepers and double-block fine-tuning rail panels: The rear moving frame 31 moves along the length of the middle sleeper car body 20. During the movement of the rear moving frame 31 along the length of the middle sleeper car body 20, the robotic arm 19 installs the double-block sleeper accessories so that the double-block sleeper and the double-block fine-tuning track panel are assembled into a whole.

[0085] In this embodiment, step 201 is specifically performed as follows: Step 2011: Control the extension of multiple transverse hydraulic rods 703. The extension of multiple transverse hydraulic rods 703 pushes the L-shaped clamping member 706 close to the uppermost multiple double-block sleepers 401 until the clamping block 707 is tightly attached to the two outer end faces of the double-block sleeper 401, and the bottom surface of the truss of the double-block sleeper 401 is attached to the horizontal surface of the L-shaped clamping member 706. The limiting rod 708 is just inserted into the web plate at both ends of the truss of the double-block sleeper 401. Step 2012: Control the upper lifting cylinder 701 to retract. The retraction of the upper lifting cylinder 701 drives the material support plate 702 and the multiple double-block sleepers 401 clamped by the material support plate 702 to rise synchronously, so that the bottom height of the double-block sleepers 401 is higher than the horizontal part of the L-shaped lifting claw 304; wherein, when the material support plate 702 rises, the guide sleeve 705 rises synchronously along the guide rod 704. Step 202, the specific process is as follows: Step 2021: Control the extension of the hook claw cylinder 305, and drive the gripper mechanism 3 and its L-shaped lifting claw 304 to move along the length direction of the upper slide rail 310 through the transverse component until the L-shaped lifting claw 304 moves to the bottom of the double-block sleeper 401 located at the rear edge of the gripping and lifting. Step 2022: Control the hook claw cylinder 305 to retract. The retraction of the hook claw cylinder 305 drives the L-shaped lifting claw 304 to rise until the hook claw cylinder 305 returns to its original position. Step 2023: Control the extension of the limit cylinder 301. The extension of the limit cylinder 301 pushes the limit block 303 down until the limit block 303 fits against the two inner end faces of the double-block sleeper 401.

[0086] In this embodiment, in actual use, the double-block fine-tuning track panel can refer to the double-block fine-tuning track panel system and method of double-block ballastless track composed of two rails and multiple sets of adjustment mechanisms in patent CN202311507129.7.

[0087] In this embodiment, the intelligent sleeper-sharing trolley is moved to the construction requirement area in step 101. The specific process is as follows: When the front hydraulic outrigger 508, the middle hydraulic outrigger 12, and the rear hydraulic outrigger 17 are in a retracted state, the hydraulic motor, the first traveling wheel 13, and the second traveling wheel drive the middle cloth pillow body 20 and the front assembly 10 and the rear assembly 30 connected to the middle cloth pillow body 20 to move as a whole until they move to the area that meets the construction requirements. Then, the front hydraulic outrigger 508, the middle hydraulic outrigger 12, and the rear hydraulic outrigger 17 extend together so that the bottom of the hydraulic outriggers is in close contact with the construction area.

[0088] In this embodiment, the packaged double-block sleepers consist of four layers of double-block sleepers, with four double-block sleepers in each layer. The number of double-block sleepers in each layer is the same as the number of transverse hydraulic rods 703, and can be adjusted according to actual requirements.

[0089] In this embodiment, it should be noted that when the packaged double-block sleepers are loaded onto the sleeper tray 4, the front moving frame 1 is first moved towards the rear moving frame 31 so that the sleeper tray 4 is exposed. Then, the packaged double-block sleepers are loaded onto the sleeper tray 4 by a crane or forklift.

[0090] In this embodiment, the multiple transverse clamping members on the clamping and lifting mechanism 7 in step 104 correspond to the multiple double-block sleepers located on the top layer. The specific process is as follows: The upper lifting cylinder 701 extends and retracts, driving the material support plate 702 to move up and down along the guide rod 704 through the guide sleeve 705 until it corresponds to multiple horizontal clamping parts on the clamping lifting mechanism 7 and multiple double-block sleepers located on the top layer.

[0091] In this embodiment, the front moving frame 1 and the rear moving frame 31 move, specifically as follows: When the travel motor reducer 203 is working, the rotation of the travel motor reducer 203 drives the gear 202 to rotate. Under the meshing of the gear 202 and the intermediate rack 905, the gear 202 rolls along the intermediate rack 905, and the synchronous travel slider 204 moves along the intermediate slide rail 904.

[0092] In this embodiment, during specific implementation, multiple design positions for placing the double-block sleepers 401 are marked sequentially from the rear movable frame 31 to the front movable frame 1. The number of design positions is determined according to the construction design requirements and is not specifically limited.

[0093] In this embodiment, specifically during implementation, in step 204, the gripper mechanism 3 lowers the clamped double-block sleeper 401, specifically as follows: The hook claw cylinder 305 is extended, which drives the L-shaped lifting claw 304 to descend until the bottom surfaces of both ends of the double-block sleeper 401 are in contact with the top surface of the vertical frame beam plate 901 on the middle sleeper car body 20 at the first designed position. The control limit cylinder 301 retracts, and the retraction of the limit cylinder 301 pushes the limit block 303 to rise until the limit block 303 releases the restriction of the two inner end faces of the double-block sleeper 401. Continue to control the extension of the hook claw cylinder 305, and the L-shaped lifting claw 304 continues to descend and disengage from the double-block sleeper 401. Then, through the transverse movement component, the gripper mechanism 3 and its L-shaped lifting claw 304 move in the opposite direction along the length of the upper slide rail 310 until the L-shaped lifting claw 304 moves out of the double-block sleeper 401. Then, control the hook claw cylinder 305 to retract and reset.

[0094] In this embodiment, threaded spikes, elastic clips, gauge baffles, rubber pads, height adjustment pads, and other double-block sleeper accessories are respectively arrayed and inserted on the first insertion position 803, the second insertion position 804, the third insertion position 805, the fourth insertion position 806, and the fifth insertion position 807. In actual use, the accessories can be adjusted as required to meet the construction requirements. In this embodiment, step three is as follows: Step 301: Sequentially insert threaded spikes, spring clips, gauge baffles, rubber pads, and height adjustment pads into the accessory rack 802 of the rear movable frame 31. Step 302: Operate the rear moving frame 31 to move along the length of the middle sleeper body 20, and during the process of the rear moving frame 31 moving along the length of the middle sleeper body 20, control the robotic arm 19 to install the rubber pad and the height adjustment pad on the rail bearing groove of the double-block sleeper 401 in sequence. Step 304: The rear moving frame 31 is reset, and the rails 21 of the double-block fine-tuning rail panel are hoisted and installed on the double-block sleeper 401. Step 305: Operate the rear moving frame 31 to move along the length of the middle sleeper car body 20, and during the process of the rear moving frame 31 moving along the length of the middle sleeper car body 20, control the robotic arm 19 to take out the gauge baffle, elastic bar, and threaded spike in sequence and place them on both sides of the rail 21. Step 306: Move the rear moving frame 31 along the length of the middle cushion body 20. During the movement of the rear moving frame 31 along the length of the middle cushion body 20, the vertical cylinder 812 extends and drives the rotary power mechanism 814 to approach the threaded spike to fasten the threaded spike. 307. Lift and move the installed double-block sleepers and double-block fine-tuning rail panels as a whole for installation.

[0095] In summary, this invention is reasonably designed. By clamping, lifting, and placing the double-block sleepers, it achieves the separation of the double-block sleepers and assembles the separated double-block sleepers and double-block fine-tuning rail panels into a whole. Subsequently, the double-block sleepers and double-block fine-tuning rail panels are installed as a whole, which can quickly complete the construction of double-block sleepers, reduce frequent manual intervention, save manpower and material resources, and improve construction efficiency.
